It’s not a pie full of fruit, but the Raspberry Pi is awesome in its own way. Been hearing a lot about this little computer, but no idea what it’s really about? Here’s what you need to know.

It might be small, but the Raspberry Pi is capable of so much. That’s why there is so much information about the computer, and this is where things can get confusing.

We’re going to help you get to grips with everything Pi-flavored, looking at:

What’s the Deal With Raspberry Pi?

Released in 2013, the Raspberry Pi is a credit card-sized computer initially intended to encourage the teaching of computing in schools. Also equipped with GPIO pins an USB ports, the computer has gone through several iterations.

As of this writing, the Raspberry Pi 3 is the main version, although a slimline alternative, the Raspberry Pi Zero W is also available.

The Raspberry Pi carries on a British tradition in computing: it is built using the ARM architecture, and the ease with which it can be used to interact with other hardware is reminiscent of the Sinclair computers of the 1980s.

Projects You Can Do With a Raspberry Pi

Its small size, low power consumption, and use of Linux operating systems (usually Raspbian) has led to the Pi being embraced as a solution to many problems.

However, it’s also been used widely as a media center, as well as a retro gaming device. There are so many ways you can use the Raspberry Pi, it can seem a little bit overwhelming.

Think of it this way: consider how flexible your desktop computer is. Then shrink that flexibility down into a device the size of a credit card.

From helping you monitor your network to acting as a print server for older printers, the Raspberry Pi does almost everything. Oh, it’s also been into space, too: a Raspberry Pi was taken on board the International Space Station by British astronaut Major Tim Peake in 2016.

Where Can You Buy a Raspberry Pi?

Millions of Raspberry Pi computers have been produced, and they can be bought from many locations online and off. But if you want one as soon as possible, the best place is Amazon.

Here, you can choose between a single Pi on its own, or a kit with a case, cables, and microSD card. If you choose the former, you’ll need to ensure you have those components already.

What Is a Raspberry Pi 3?

As noted, the current version of computer is the Raspberry Pi 3. This device, launched in 2016, has superior hardware to the earlier versions (and even the Raspberry Pi Zero). It features a quad core 1.2GHz 64-bit ARM processor, 1GB of RAM (which is shared with the graphics processor), and on-board wireless networking and Bluetooth.

All Raspberry Pis require a microSD card for installing the operating system on, although it is possible to boot a Pi 3 from USB.

A Raspberry Pi 3 has four USB ports, an Ethernet board, and HDMI video output. There’s also a 3.5 mm TRRS jack and MIPI display interface for connecting an LCD display (the official touch screen device is particularly good), and a MIPI camera interface for connecting a camera.

Clearly this is a powerful little box of tricks. The hardware specification even makes the Raspberry Pi 3 ideal as a basic desktop replacement.

Almost everything has been shrunk down, reducing the width of the board and the height. One USB micro B data port is present, along with a similar power-only port. There’s also Mini-HDMI for video and audio output.

A basic Raspberry Pi Zero is available for under $10, although you should turn your attention to the Raspberry Pi Zero W. This wireless variant features onboard Bluetooth and Wi-Fi, just like the Raspberry Pi 3.

Meanwhile, if you need a slimline Raspberry Pi but also need the GPIO pins, the Raspberry Pi Zero WH was released in late 2017.

With all of this done, it’s time to plug in the Raspberry Pi, and watch as a whole new world of computing opens up to you. Log in with the default credentials—username pi and password raspberry—then change them!

As soon as the cable is connected, the Pi will boot. There is no power switch.

The Raspberry Pi 3 is best powered with a reputable connector, one that provides the required 2.5 Amp; as long as the power supply provides this, you should have trouble-free computing. But how do you turn a Raspberry Pi off?

Remote Control a Raspberry Pi With SSH, VNC, or RDP

The Raspberry Pi needs a display, as well as a mouse and keyboard to interact with it. But these don’t necessarily need to be connected. Instead, you could just plug your Raspberry Pi into your router and connect remotely.

You can even enable SSH on a Raspberry Pi before you’ve used the computer. While the microSD card is still in your PC, browse to the /boot/ directory (if you’re using Windows, this is the only part of the microSD card you’ll be able to see) and right-click in the folder window.

Here, select New > Text Document and name it ssh. Make sure you remove the .txt extension. When your Raspberry Pi boots into Raspbian for the first time, the operating system will check for the ssh file, and enable it.

You can then remote connect over SSH using a suitable application (PuTTY is popular on Windows) and the default username and password.

The Raspberry Pi is a great device for children, there’s even a version that is focused at youngsters, called Kano.

This combines a Raspberry Pi with some Lego-esque principles: easy to hold components, a click-together case, and clear, bright instructions. If you have little ones that you want to encourage into the world of computing, this is a good start.

While you can’t eat a Raspberry Pi, it’s an awesome little computer than can do so much more than fill your belly and rot your teeth.
